Abstract

The present invention is directed to a hybrid cabled cord comprising: at least two yarns having different properties and an unbalanced configuration wherein the hybrid cabled cord has improved tensile strength retention. In a preferred embodiment one of the two yarns comprises polyethylene terephthalate and the second of at least two yarns comprises polyethylene naphthalate and the coring level is between about 3% to about 15%. The present invention is also directed to a process for making a hybrid cabled cord comprising the steps of supplying at least two yarns having different properties to a direct cabler, and cabling the at least two yarns using the direct cabler to achieve a hybrid cabled cord having a coring level which is not zero. The present hybrid cabled cord may be used in tire cord for rubber reinforcement in passenger car tires, van tires, light truck tires, or motorcycle tires.

Claims (12)

1. A process of manufacturing a hybrid cabled cord comprising the steps of:

(a) supplying at least two yarns having different properties to a direct cabler, and,

(b) cabling said at least two yarns using said direct cabler to achieve a hybrid cabled cord wherein said coring level is equal to or greater than about 3% up to and no greater than about 15%.

2. A process of manufacturing a hybrid cabled cord comprising the steps of:

(a) supplying at least two yarn having different properties to a direct cabler, and,

(b) cabling said at least two yarn using said direct cabler to achieve a hybrid cabled cord wherein said coring level is equal to or greater than about −15% up to and no greater than about −3%.

3. The process according to claim 1 wherein one of said at least two yarn is polyethylene naphthalate.

4. The process according to claim 1 wherein at least one other of said at least two yarns is polyethylene terephthalate.

5. The process according to claim 1 wherein one of said at least two yarns is aramid.

6. The process according to claim 2 wherein one of said at least two yarns is polyethylene naphthalate.

7. The process according to claim 2 wherein at least one other of said at least two yarns is polyethylene terephthalate.

8. The process according to claim 2 wherein one of said at least two yarns is aramid.
